Measuring Endoscope Apparatus, Program and Recording Medium

1. A measuring endoscope apparatus comprising: an endoscope that photoelectrically converts an image of an object to generate an imaging signal, a signal processing section that processes the imaging signal to generate image data, a distance-measuring section that calculates object distances for a plurality of points on the object using the image data, a display section that displays the image of the object based on the image data, and a measuring section that determines a display appearance of a first mark to indicate an inclination of the object in a depthwise direction of the image based on the object distances for the plurality of points on the object, wherein the measuring section determines the display appearance of the first mark such that one portion of the first mark that corresponds to part of the object that is closer is larger than another portion of the first mark that corresponds to part of the object that is farther away, wherein the display section displays the first mark.

2. The measuring endoscope apparatus according to claim 1 , wherein the measuring section calculates a size of another mark that indicates a size of the object based on another object distance and a view angle of the endoscope.

3. The measuring endoscope apparatus according to claim 2 , wherein the measuring section calculates a size of the another mark on the object at a position apart by the another object distance based on the another object distance, the view angle of the endoscope and a display size of the another mark.

4. The measuring endoscope apparatus according to claim 2 , wherein the measuring section calculates a display size of the another mark based on the another object distance, the view angle of the endoscope and a size of the another mark on the object at a position apart by the another object distance.

5. The measuring endoscope apparatus according to claim 2 , wherein the display section displays the image of the object and displays the another mark overlying an aim indicating an object distance measuring point of the another object distance.

6. The measuring endoscope apparatus according to claim 2 , wherein the display section displays the image of the object and the another mark and displays a value of a size of the another mark on the object at a position apart by the another object distance.

7. The measuring endoscope apparatus according to claim 2 , wherein the display section displays the image of the object and displays the another mark around a frame of the image of the object.

8. The measuring endoscope apparatus according to claim 2 , wherein the display section displays the image of the object and the another mark and displays the another object distance.

9. The measuring endoscope apparatus according to claim 1 , wherein the measuring section further calculates distances among the plurality of points on the object based on spatial coordinates of the plurality of points, and calculates a size of a second mark that indicates a size of the object and a distance between two points on the object based on positions of a plurality of points on an image forming surface of the endoscope corresponding to the plurality of points on the object.

10. The measuring endoscope apparatus according to claim 9 , wherein the first mark and the second mark are identical.

11. The measuring endoscope apparatus according to claim 1 , wherein the measuring section further calculates distances among the plurality of points on the object based on spatial coordinates of the plurality of points on the object, and calculates a size of a second mark that indicates a size of the object based on a preset numerical value indicating a distance on the object and the distances among the plurality of points on the object calculated by the measuring section.

12. The measuring endoscope apparatus according to claim 11 , wherein the display section further displays the distances among the plurality of points on the object.

13. The measuring endoscope apparatus according to claim 12 , wherein the display section displays the distances among the plurality of points on the object over the image of the object.

14. The measuring endoscope apparatus according to claim 12 , wherein the display section displays the distances among the plurality of points on the object at a location other than where the image of the object is displayed.

15. The measuring endoscope apparatus according to claim 12 , wherein the display section displays the distances among the plurality of points on the object in a vicinity of the second mark.

16. The measuring endoscope apparatus according to claim 1 , wherein the distance measuring section calculates spatial coordinates of the plurality of points on the object and calculates object distances to an image forming surface of the endoscope from the points on the object using the image data.
